Abstract

Method and apparatus for seismic data processing estimate primaries and/or internal multiples by solving a two-way wave equation using first and later arrivals from each layer of an underground formation explored using waves, and summing contributions of the layers to the primaries and/or the internal multiples, without using adaptive subtraction.
